More power to you, if that's your opinion. As for him surviving it, that was in an after-credits scene, which as I said, devalues the sacrifice in the first place. Also, starting anew, after everything he's been through, isn't exactly his only course here either. Also, his more human side was shown, even if in a flash, in both GOW 2 and GOW 3, with Athena and Pandora. The former when he showed instant remorse for stabbing and killing her, before retreating back into his anger, as he doesn't know how to do anything else at that point, and the latter, where he started to see her as a second daughter of sorts.
